- generic/nsf.c: Aligned error messages for parameter options; Re-arranged control flow in ParamOptionParse() slightly, do allow for [string is] types being used as options of disposition types. Refactored code slightly (e.g., removed unneeded, intermediary Tcl_Objs). - tests/disposition.test: Extended test suite, in particular, for covering multiplicity types as parameter options of disposition types. - tests/parameters.test: Adjusting for rephrased error messages.
